Longgong (Dragon Palace) Waterfall was formerly known as Shuan-Shui-Tan (Double Waterfall Pools) because there is also a Leiyin (Thunder Sound) Waterfall under the Dragon Palace Waterfall. Both waterfalls pour water into the same cliff circle, but each waterfall has its own waterfall pool, forming a very rare terrain of double waterfall pools. It is the only place in Taiwan with such unique scenery. The height of Dragon Palace Waterfall is about 120 meters, and 60 meters for Thunder Sound Waterfall: one small one large, and one high one low, the effortless appreciation of the reputable scenery along the trail always attracts lots of tourists.
